Use two coils with exactly the same radius and number of turns, arrange them coaxially and make the distance equal to the radius, this kind of coil combination is called Helmholtz coil. It can generate a very weak magnetic field up to hundreds of Gs; the coil has a large uniform area, an open space for use, and easy operation. It can realize one-dimensional, two-dimensional, and three-dimensional combined magnetic fields, and can provide AC and DC magnetic fields. The current has a good linear relationship with the magnetic field. It is suitable for various research institutes, universities and enterprises to do material magnetism or testing experiments, applied to materials, electronics, biology, medical treatment, aerospace, chemistry, applied physics and other disciplines. Its main purpose: to generate standard magnetic fields; Cancellation and compensation, geomagnetic environment simulation, determination of magnetic shielding effect, electromagnetic interference simulation experiment, Hall probe and various The calibration of a kind of magnetometer, the study of biological magnetic field and the study of the magnetic properties of matter.
Hunan Forever Elegance Technology Co.,Ltd is in the forefront of the international counterparts in the generation of Helmholtz coil magnetic field. At present, we have successively developed and designed: circular, square, and octagonal Helmholtz coils. At the same time, with the help of finite element design tools, we have developed compensating octagonal Helmholtz coils. The uniformity area is increased by eight times.
When users choose Helmholtz coils, please provide the magnetic field strength, uniformity range and uniformity requirements according to the experimental needs. We can provide users with detailed design methods and selection of supporting power supplies in the shortest time.
